Application filed January 24, 1916. Serial No. 74,924.

To alt 'lv/tom t may conce'n Be it known that I, IsRAnL MAROUS, a citizen of the United States, residing at lVinthrop, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Ground-Con-v uectors; and I do declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in ground connectorsof the type clamped to embracea pipe or suitable ground conductor, and adapted to make a good electrical connection therewith.

The objects of this iuvention are 'to provide a simple, practical, and eflicient connector which is adapted to be adjustable, so that the same may be lconnected to various sizes of conductors, and which will form a very secure connection therewith. v

A further object of the invention is to provide a device which is siinple and durable in construction, inexpensive to manufacture, and one which will be Very efficient in operation.

With these and numerous other objects in view, my invention consists of the novel features of construction, combination and arrangement of parts which will be herein referred to and more particularly pointed out in the specification and claim.

In the accompanying' drawings: Figure 1 is an end view of the connector showing the same applied to a pipe; Fig. 2 is a central Vertical section; Fig. 3 is a side elevation; Fig. 4 is a similar view to Fig. 3, taken from the opposite side of the connector, and Fig. 5 is a horizontal section taken on the line 5 5 of Fig. 1.

i Inl describing my invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views, and in which the numeral 1 designates a lexible metallic strip, of equal width throughout its entire length, and which has adjacent one end 2, a plurality of longitudinally extending spaced apertures or openings 3. The other end 4 of the metallic strip 1 has a single aperture or opening 5 therethrough disposed a predetermined distance from the same. A. portion of the strip betweensaid opening 5 and the end 4, adjacent said end 4 is bent upwardly substantially U-shaped, having its ,the fianges of the same will extend side edges 6 lying parallel and disposed in' a plane substantially at right angles to the plane of the remaining side edges of the' strip 1. -g v The flat metallic strip 1, owing to its flexibility, is adapted to surround the pipe or other suitable conductor 7, as clearly 'shown in Fig. 2 of the drawings, and is adapted to have the aperture 5 adjacent the end 4 of the same disposed in alinement With one of 'the apertures 3 through the opposite end 2 of said strip. Owing to the fact that the end 2 of the strip is provided with a plurality of longitudinally spaced openings, it will be obvious that this metallic strip Will be adjustable to various sizes and shapes of suitable conductors, as the single opening 5 at one end of the strip may be disposed in alinement with any one of'the various openings 3 in the opposite end of the strip, in accordance Withv the size of the conductor which it surrounds. T vWhen in position around a conductor,

shown in Fig. 2 of the drawings, and o disposed that the aperture or opening 5 is llin alinement with one of'the openings in the opposite end of the strip, a pair of side plates 8 and'9 are adapted to be ositioned on the outer surface of said ends o the ban v the side late 8 being disposed adjacent the; end of the band, while the side plate 9 is positioned adjacent the' opposite end 2 of the same. 'The side plates 8 and 9 are provided and 11, which are adapted to aline with the corresponding openings 5 and 3 in the oppo-` w site ends of the strip, when in position. i The'\ opening 11 which is disposed; through the side plate 9 is internally screw threaded for a purpose to be hereinafter more'full'y set forbh. l The side plates 8 and 9, have projecting from their free edges, obliquely inclined out-- wardly extending flanges 12' which are i100 adapted to be positioned adjacent'the top of the conductor 7, as clearly shown in Fig.

2 of the drawing. The side plates 8 and 9, f

and the projecting flanges l12 of the sameiare substantially the same size when positioned 105.

at opposite ends of thelmetallic strip and down'- wardly an equal distance along the outer surface-of the strip 1.

The side plates, on adjaoent ends of the 11.0

band, are adapted to hold the said band around the cond uctor 7 by means ofa headed eo -s with centrally disposed apertures 10 i screw 13, which is adapted to be positioned through the -alining openings in 1the band and plates. and disposed in threaded engagement with the opening ll through the side plate 9. This screw 13 has a lock nut 14 on its outer end, which is adapted upon being moved thereon, to lock the side piates and ends of the band together to securely clainp the said band around the conductor. When this band is positioned as above de- 'scribed, it will be obvious that the end lof the same will project a certain distance above the opposite end thcreot', and owing to the tact that the side edges of said projccting end are upturned to .torni a substantially U-shaped portion, the same is adapted to act as a terminal so that it nia)Y be easily clainped around the end of a lead wire.

The projecting fiangcs 12 on the lower edges ot' the side plates 8 and space said giates froin coming in close proxin'iity to the conductor 7 when the parts are clainped together.

The above description, and the accompanying drawings, describe and 'illustrate aV ground clalnp, which is forined of a very simple and eflicient arrangenient of a flexible band, two side plates with projecting tlanges, and means to clan'ip the parts in position when surrounding a conductor. The

fleXible metallic band may be forined of anysuitable material, and the projecting end 4 of the saine with the U-shaped extreniity forms an integral terminal portion which may be easily engaged with the end ot' a wire. The inanner of applying this device to use and the operation thercof will be readily understood, and it will be seen that I have provided a simple, inexpensive, and

eilicient means for carrying out the objects of this invention. If desi1'ed,the fiexible inctallic band nia v bensed as above described without the necessity of exnploying the side plates S and 9, as the said band .would be adapted to seeurely engage the conductor 7 it' held together only b v the screw li' and nut ll.

1 claini as niy invention:

In a device of the class described, a flexible nietallic strip adapted to surround a suitable conducto and having its end portions disposed adjaeent each other with alined apertuies tln'retln'ough, a projmting portion on one end ot' said strip to forin a connecting terminal, side plates of equal width and greater thicknesses than said strip positioned against-the outer surfaes ot' the end portions and having apertures therethrough alining with the apertures through said ends, one of said plates having its apertures screw thrcaded7 a looking' screw eixtending through the alining apertures in the platesand end portions and operatively engaging said threaded aperture in one of tlnl plates, a lock nut on the onter end of the screw adjacent said plate, and obliquely inelined outwardlyv extending spacing flanges projecting troin the inner edges ot said plates and adapted to space said plates from the eonductor and to additionally elaxnp the strip around the .'anie.

ln testiinony whereot' I have hereunto set inv hand in presence of two subscribing witnesses.
